In the case shown said head has the form of the frustum of a cone. The ings, and to letters and figures 0 reference spindle 1 carries the supporting and e ector marked thereon, which form a part of this s specification.

ter the rollers 5 have been moved out of contact with said capsule. In line with the spinning-spindle is arranged At its inprovided with a head 7, the stem in said inner end inst endwise mog the follower 71 revoluble head 7 is Patent of the United nder date of ()ctober n lmpression in the cup shaped capsule blank spring-pressure from the top or'cover of the capsule, so that the sleeve 3, which has now been released, can effect the ejection of the finished capsule from the end 2 of the spinning-mandrel by the pressure of its spring.

Fig. 1 shows the position of the parts im mediately before the completion of the operation of spinning.

The mechanism which feeds the ejected blank to the edge-trimming device (which is of known construction) for cutting off the irregular edge thereof and afterward deposits the said blank, for example, into a suitable receptacle comprises a carrier provided at one end with a grasping and feeding fork 8, which is shaped to correspond with the form of the finished capsule and which consists of a sleeve having two slots. The stem or supporting-arm 9 of this sleeve is preferably arranged obliquely, as shown, and can be moved longitudinally in fixed guides 10 and 11. The lower end of this arm 9 rests either directly or b means of a roller on a ste ped cam 12, of w 'ch the shaft 13 turns in a earing 15, mounted on the under side of the table 14 of the machine, and is driven by means of chain or other suitable driving-gear from a rotating shaft 16 at the same angular velocity as the ,shaft 17 of the cam 6. On the shaft 17 are mounted two cams 18 and 19, which act either directly or by means of the levers 20 and 21, as shown, on two corres ondingv slide-bars 23 and 24, which can s ide parallel to the spinning-mandrel 1 in a uide-bracket 22, but cannot rotate. The paths of these slide-bars extend through the center line of the arm 9 of the fork or throu h the path thereof. The slide-bars 23 and %4 are each provided with an adjustable collar 25 and with a sprin 26, which brings back the corresponding s ide-bar to its original position (toward the right in Fi 1) as soon as the cam 18 or 19, respective y, ceases to act. The slide-bar 23, arranged nearer to the s inning-spindle, has at its end a head 27 whic is of such dimensions that it can ass freely through the opening or jaw of the ork 8, approximately in front of it. This head, which serves for pushing the capsule 4 for the time being in the fork onto t e edge-trimming device and then for bringing it back again into the fork, is provided for this purpose with two or more spring-arms 28, arranged around its periphery, and also, if desired, with an insert 4, of india-rubber, as shown in Fig. 4, in order not to damage the impression on the top of the capsule. The arms 28 themselves can also be covered on the inside with india-rubber or other suitable yielding material in order to permit a certain withdrawal of the capsule after the edge has been out ofi. The second slide-bar 24, lying beneath slide-bar 23, acts, by means of its head part 29, as an ejector which transfers emcee the finished capsule in the fork 8, while the latter is in its lowest position, out of the said fork into a channel 30 arranged in front of it.

In front of the upper slide-bar 23 and coaxially therewith is arranged the edge-trimming device, which consists of a carrier made of similar form to the spun capsule and in the present case of a cone 31, which is, however, shorter than the blank, so that on pushing the blank onto the cone the edge of the blan projects beyond that of the cone. The latter is provided at this edge with a projecting knife 32 and adjacent thereto with a radially-mounted stri per 33 for the purpose of preventing the ro l ng inward of the cut-off edge of the ca sule. The spindle 34 of the cone 31 (whic spindle is rotatable in the hearing-bracket 22 and can make a slight movement in an axial direction and is pressed by means of a spring 35 against the fork 8) is provided with a band or chain roller 36, which is set in rapid rotation from any rotat ing part of the machine. In practice the sp ndle 34 may be provided at its inner end with an abutment-for instance, in the form of an annular flange k-to limit its movement toward the right, Fig. 1. The spindle 34 may be driven, as stated, from any rotating element of the machine, either from the prime motor (not shown) which drives the s inning-spindle or from the shaft 13, suita l prolonged and carrying a chain or belt pul ey 1 3 of the required speed. The method of operation of the arrangement above described is as follows: As soon as the eccentric part a b of the step ed cam 12 ha spassed the end of the stem 9 o the carrier the fork 8 is raised to its highest position, at which point it stands coaxially with the spinning-mandrel 1 and surrounds the head 7, which is still in contact with the spun capsule, Fig. 1. While the concentric part b c of the step ed'cam moves past the end of the stem 9 t e fork 8 remains immovable in the said highest osition, during which time the head 7 is wit drawn and the splun capsule 4 is ejected b the sleeve 3 (whic hasbeen released on t e raising of the spinning-rollers 5) and is thereby pressed into the fork 8 in front of it, whereupon the stem 9 falls from the step c of the cam 12 directly onto the concentric part d e thereof. The fork 8 containing the capsule, is now in the mi -position and is coaxial with the slide-bar 23 and the edge-trimming device 31 32. While the stepped cam 12 moves from d to e the fork remains in its mid-position, during which time the slide-bar the cam 18 on the shaft 17', so that the head 27, by means of the spring-arms 2 8, simultaneously pushes the capsu e 4 onto the cone 31 of the edge-trimming device, in which 0 eration the ca sule 4, clamped between t e arms 28 and tting loosely on the smooth IIC 23 is moved forward by Gone 31, does not rotate with the said cone, feed the sha ed article to the carrier, means 65 so that -the knife 32 cuts off the edge of the to transfer the article therefrom to the trim- I capsule Iprojecting beyond the edge of the mer, meansv to return the trimmed article to cone. irectly after this the head 27 is the carrier, means to move the carrier from again drawn back, in which operation it carthe trimmer to the receiver and means to ries the now finished capsule with it bymeans eject the finished articles from the carrier and 70 of the spring-arms 28 and brings it back nest or telescope the same on the receiver. again into the fork 8, which is still in the mid- 6.
